Chrysanthemum plant named ‘Synberna Yel’

ABSTRACT

A new  Chrysanthemum  plant named ‘Synberna Yel’ particularly distinguished by the large, long lasting flowers with yellow ray florets, rounded plant habit with yellow-green foliage, a garden  Chrysanthemum  with an early flowering natural season habit.

Latin name of the genus and species of the plant claimed:Chrysanthemum×morifolium.

Varietal denomination: ‘Synberna Yel’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically knownas Chrysanthemum×morifolium, and hereinafter referred to by the varietyname ‘Synberna Yel’.

‘Synberna Yel’ is a product of a planned breeding program. The newcultivar has large, long lasting flowers with yellow ray florets,rounded plant habit with yellow-green foliage, a garden Chrysanthemumwith a natural flowering season of about mid-September.

‘Synberna Yel’ originated from a hybridization made in October 2004 in acontrolled breeding environment in Salinas, Calif. The female parent wasthe unpatented proprietary plant designated ‘01-M16’ with white spoonedshaped ray florets and a less vigorous plant habit.

The male parent of ‘Synberna Yel’ was the proprietary plant designated‘Yogwendolyn’, U.S. Plant Pat. No. 17,533, with white ray florets and aone week faster natural season flowering response. The resultant seedwas sown in June 2005 in Alva, Fla.

‘Synberna Yel’ was selected as one flowering plant within the progeny ofthe stated cross in the late October 2005 in a controlled environment inAlva, Fla.

The first act of asexual reproduction of ‘Synberna Yel’ was accomplishedwhen vegetative cuttings were propagated from the initial selection inDecember 2005 in a controlled environment in Alva, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plantinitiated in December 2005, and continuing thereafter, has demonstratedthat the combination of characteristics as herein disclosed for‘Synberna Yel’ are firmly fixed and are retained through successivegenerations of asexual reproduction.

‘Synberna Yel’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada onOct. 30, 2009 (09-6761). ‘Synberna Yel’ has not been made publiclyavailable more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined tobe basic characteristics of the new variety. The combination of thesecharacteristics distinguishes this Chrysanthemum as a new and distinctvariety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliagecharacteristics of ‘Synberna Yel’ with colors being as true as possiblewith an illustration of this type. The photographic drawing shows aflowering potted plant of the new variety, and a close-up of theflowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs weretaken in Gilroy, Calif. in October 2009 under natural light. Theseplants were grown in an outdoor trial. These plants were about 12-14weeks old.
